WebAug 3, 2024 · The find () method will then check if the given string lies in our string. It will return the size of the sub-string including the '\0' terminating character (as size_t ). But if the string does not lie in our original string, it will return 0. With that, the function is defined like this: size_t find(const std::string& my_string, size_t pos = 0); WebC++ allows the programmer to define their own function. A user-defined function groups code to perform a specific task and that group of code is given a name (identifier). When the function is invoked from any part of the program, it all executes the codes defined in the body of the function.
